To all whoiwit may concern:

Be it known that I, ROY STONE, of the city and State of New York, haveinvented an Improvementin Means for Discharging Ashes from `Steamboatsand other V essels, of which the following is a specification.

Efforts have heretofore been nnule to discharge ashes from the tire-roomof steam vessels by means of a rising disch. 4'5e-trunk into which thejet of water is forced at the lowerend. I, however, find that inpractice the column of water is liable to become s o heavy, both by itsaltitude and by the ashes carried up with the water, that theactuatingjet has not sutlicient power to eject the ashes and water fromthe rising pipe. To obviate mospheric air, which, commingling with thewater and the ashes, renders the column sufficiently light to preventthe force of the jet b eing' overpowered by the weight of the column,thus lessening the force of water required for a given lift andpreventing the obstruction ot' the apparatus by the ashes being dumpedtoo quickly into the receptacle for the same.

.In addition to the foregoing diiiiculty, it often happensA that a largebody of ashes will' be vdumped into a receptacle in the apparatusprevious to the jetof water being turned on, and when such jet is turnedon it has not sufficient momentum to act with the required power, andthe ashes are simply drawn into the apparatus sufficiently to clog itup. l"l lprevent this ldifficulty by providinga three' way cock inthepipe-leadingYv from the pump and an external discharge-pipe, softhat thepump may be brought fully into action and the water discharged overboardat its maximum velocity before the ash injector is brodght into actionby turning the three-way cock.

In the drawings, Figure l represents my improved apparatus in theformadapted to ocean vessels, in which the discharge-pipe can passdiagonally from the fire-room to the side of the-vessel. Fig. 2 is asection of the water-supplying pipe and three-way cock, and

3 is a section of the ash-receiving vessel in the forn v especiallyadapted to river and coasting vessels.

The rising p ipe A maybe vertical, as shown in Fig. 3, or at aninclination, as shown in Fig.

l, and there is a bend or elbow B connecting the rising portion with thehorizontal, or nearly horizontal, discharge pipe C, that passes throughthe side of the vessel or otherwise, so that the ashes may be dischargedoverboard or into a lighter. I find that the upward flow of the ashes isliable. to injurev the bend or elbow B by internal abrasion. I thereforeprovide a removable lining B, which forms a shield, and it may be madeof metal that is the least liable to abrasion, and form a completeshield around the inside of the pipe, or only to that portion of theinte-A rior of the pipe the most liable to injury. The rising pipe A is4provided at its lower end with an injecting-nozzle D at the end of thewater-pipe E, and this pipe leads to a suitable pump tor the supply ofwaterunder pressure, and at F is a three-way cock and a discharge-pipeG, so that when the pump is started the water is to be passed throughthe pipe G until the pump attains its maximum velocity, and then thethree-way cock F is turned into the position shown in Fig. 2, so as tosuddenly open the water-way to the injectingfnoz` zle D. This nozzle Dis at the lower end of the rising pipe A and axially in line, or nearlyso,.

with the same, and at one side of the lower end of the rising pipeA isan ash-receiver H in the form'ot a troughor -funnel, the lower endopening into the sideof the risiiig pipe A. This ash-receiver H may bewithin a box I, as represented in Fig. 3, so that any surplus ashes orwater may fall over into this box; but I prefer and generally use ahopperf shaped receiver H, as shown in Fig. l, with a nozzle or pipe Kfor the supply of water into the ash-receiver for causing the ashes topass down into the rising pipe A. The Water may be supplied to thisnozzle or pipe by the hose L, Fig. l, and in instances where thetire-room is limited in its size the ash-receiver H may' be made movableand held in its position by the button N upon the bulk-head M,separating the fire-room from the 'coal-bunker. In this case it isadvantageous to make use of a pipe and stop-cock O for the supply ofwater into the hopper shaped ash-receiver, such IOO pipe and stop-coclcbeing fastened to the bulkhead M.

Under all circumstances I provide for the introduction of air at thelower end of the rising pipe A, and with this object in view the ashesshould be placed in the receiver H in such a manner that air inaydraw inabove the ashes and below the upperedge 2 of the opening into the pipeA, so that as the col umn of water from the nozzle I) mixes with theashes and carries them up in the rising pipe A air will also be drawn inwith the jet and mingled wit'hthe water sufficiently to lessen thewcightofthe column and prevent it weighing more than the force of the jet canovercome, because if the ashes become clogged in the uprising pipe A thewater will pass outl into the ash-receiver ll and the tireroom. h

As an additional protection against the rising pipe A being simplyiilleflwith ashes and water, an air-pipe P is provided a little dis`tance above the edge 2 of the ash-inlet, and in this air-pipe P, Iprefer to use. an automatic valve Q, that opens inwardly the mo mentthere is a vacuum action or minus pressure in the pipe A, caused by thewater from the nozzle l) rushing past the air-pipe P when the ashesclose the inlet at the bottom end of the ash-receiver. ,Therebydiiliculty resulting from the clogging of the pipe A with a column ofashes is prevented.

lVhere the ash-reeciver Il is removable, as in Fig. l, it is preferableto place the air-pipe P adjacent to the bulk-head M, with the automaticvalve Q at theupper end.

A pipe and cock R may be provided, as shown in Figr. l, to draw ofi.water from the pipe A, and this water may run to the bilge. The cock maybe operated by the handle and rod R', connected to an arm upon the valvestem of the cock.

I claim as my inventionf 1. The combination, with an apparatus forejecting ashes and similar material, of a rising pipe having an"openinbrnear the lower end, an injecting-nozzle in the line of the axis of thepipe, and au ash-receiver connected with the rising pipe and having anopeningat thebottom into the rising pipe above the injector-nozzle,there being an airinlet,opcn ing above the ashes and adjacent to thewater-jet, whereby air is drawn in by the action of the waterjet andcommingled withthc same for lessening the weight of the cylumn of waterand ashes, substantially as set forth.

2. The combination, with a rising pipe having a lateral opening near thelower end, of an injecting-nozzle axial withthe rising pipe nd actingbelow the lateral inlet, and an ashreceiver abete .fluid opening intosaid inlet, and a pipefmr nupplying'watcr into the same, substantiallyas setA forth.

3. The combinatiomjn an'apparatus for ejecting ashes and similarmaterials, of a rising pipe having a lateral inlet near-the lower end,and a receiver for the ashes or similar materials connected at andrising above the lateral inlet, an. injecting-nozzle central to therising pipe, a pipe for supplying Water to the nozzle, alateraldischarge-pipe therefrom, and a three-way cock, whereby the water from apump or other supply can be allowed to attain its maximum velocity andthen be suddcnly turned through the jet-nozzle, substantially as setforth.

4.' rlhe combination, with a rising pipe having a lateral inletnear thelower end and a recei'ver connected thcreat for ashes or similarmaterial, of a jet-nozzle axial to the ris-` ing pipe, a horizontal ornearly horizontal dischargepipe above the upper enti of the risingpipe,.an arm orclbow connecting the,

rising pipe with the horizontal discharge-pipe, and a removable liningto the elbow or bend, substantially as set forth. f

5. rllhe combinatiomwith the aslrreceiver and the rising pipe having alateral opening near the lower end at which the ash-receiver isconnected, and an injectinghozzlc axial to such rising pipe, of anair-inlet pipe connectied with the rising pipe above the lateralopening, substantially as and for the purposes set forth.

6. rl`he combination, with the` rising,` pipe havnig a lateral opening,rnear the lower end, of an ash-receiver opening at its lower end into`the rising pipe, and an injecting-nozzle axiaz to such. rising pipe,and an air-inlet pipe above the lateral opening, and an automatic valveto the air-pipe, substantially as and tor the purposes set forth.

7. `The combination, with arising pipehaving a lateral opening near thelower end and the injecting-nozzle axial to the rising pipe,

of a removable ash-receiver having an opening at its lower end toconnect uilh theris'i,`
